Despite mixed results in research on student learning from drawing in science, there is growing interest in the potential for this visual mode, in tandem with other modes, to enact and enable student reasoning in this subject. Building on current research in this field, and using a micro-ethnographic approach informed by socio-semiotic perspectives, we aimed to identify how and why student drawing can contribute to student reasoning and learning. In our study, secondary school students were challenged to explore and collaboratively create explanatory representations of phenomena including through drawing. Data were generated using multiple wall- and ceiling-mounted cameras capable of continuously tracking groups of students negotiating these representational challenges. Our analysis proceeded through active and iterative viewing of the extensive video record, and the identification of themes to establish possible relationships between drawing and reasoning. Through this process, we (a) identify multiple necessary conditions and varied opportunities for student drawing to enact and enable reasoning, and (b) extend current understandings of how the particular affordances of this mode interact with these conditions to contribute to student learning in science. 相似文献
Adolescents are spending an unprecedented amount of time using digital technologies (especially mobile technologies), and there are concerns that adolescents’ constant connectivity is associated with poor mental health, particularly among at‐risk adolescents. Participants included 151 adolescents at risk for mental health problems (Mage = 13.1) who completed a baseline assessment, 30‐day ecological momentary assessment, and 18 month follow‐up assessment. Results from multilevel regression models showed that daily reports of both time spent using digital technologies and the number of text messages sent were associated with increased same‐day attention deficit hyperactivity disorder (ADHD) and conduct disorder (CD) symptoms. Adolescents’ reported digital technology usage and text messaging across the ecological momentary assessment (EMA) period was also associated with poorer self‐regulation and increases in conduct problem symptoms between the baseline and follow‐up assessments. 相似文献
AbstractCanadians have been involved in every edition of the Pan-American Games since they were inaugurated in Buenos Aires in 1951. That participation has provided thousands of Canadian athletes, coaches, and officials memorable international experiences. But the focus of Canadian involvement with the Pan-Ams has been the staging of games as a strategy for city building, city branding, and infrastructural investment. This paper examines the Pan-American Games of Winnipeg in 1967 and 1999 and Toronto 2015 as exemplars of that strategy. It argues that with the successes of those games, major games hosting has become virtually an article of faith of Canadian sport policy. 相似文献
Conclusion These case studies offer strong support for the notion that learning occurs naturally and inevitably when it flows out of
a student's desire to extend her own interests and experiences. This view was expressed strongly by the progressives (Dewey
[1963], and Kilpatrick [1928, 1952:315]) and more recently by Wilson (1971). They also represent “instances of autonomy” that
challenge our normal assumptions of student behaviour.
There are, of course, matters of the transmission of those “storehouses of knowledge” that represent the disciplines, and
matters of practicality in motivating and managing a class of students pursuing their own interests (Tytler 1983), that would
make it impractical to centre all teaching around the IRP or its equivalent. The need to include IRP's at a significant place
within the curriculum, however, is indicated not only by the student outcomes that have emerged in this study, but from the
fact that an increasing number of teachers have found it to be a satisfying method, involving a more powerful and natural
view of the student in relation to the educational process (Tytler, ibid).
The case studies have something to say about all such activities (other possibilities are described in Boomer [1983]) that
invite students to take responsibility for the serious development of their interests. They stand as examples of the way students
work outside the classroom, but also as celebrations of student independence and autonomy. Too often the schooling practices
we subscribe to tend to invalidate students' own life experiences. These case studies provide a challenge to us to find educative
ways that can match the range of abilities and dispositions that students bring with then to school. 相似文献
There are people who think and people who dream, but there are more people who do neither. The first group, those who think, do not doubt that wars will continue in the future as in the past; the dreamers, their heads swirling in roseate dreams of the universal brotherhood of all mankind, still envision the warless age. Hard headed realists know that civilization of the kind we have always had (when we have had any at all) is more likely to increase than to decrease the number of open seasons for human game. They join with the dreamers in deploring the kind of wars we now fight, but they recognize the inevitability of war and try to take proper measures for selfsurvival. Members of the third group, those who neither think nor dream, vegetate in peace time, reproduce all of the time, and the best of them get killed when war comes. During the periods of armed neutrality, which we call peace, they listen to the plans of the dreamers. 相似文献
This paper describes the development of a reliable, short questionnaire (PLSQ) to measure student perceptions of and satisfaction with quality of service in an academic library. This formed part of a wider study to evaluate student awareness and use of library services and staff support. This included the simultaneous development of a ‘factual’ questionnaire and two small scale observational studies, backed up with ‘market research‐type’ interviews to evaluate the effectiveness of the ‘help desk’ and ease of use of the computer catalogue. A ‘triangulation’ technique was thus used to provide indirect evidence that the questionnaire was validly measuring user satisfaction. The results from the initial trial of the questionnaire are described and compared with relevant findings from the ‘factual’ questionnaire and the help desk study. Though two samples completed different questionnaires, the frequency results arc either in complete agreement or mutually supportive. The help desk study results are also supportive, again suggesting that the questionnaire is a valid measure. Following statistical analyses, the final sixteen item PLSQ emerged which produces internally consistent responses and which appears to measure satisfaction with staff helpfulness and physical conditions in the library and perceptions of ability to find information and knowledge of CD‐ROM and other services. 相似文献
Government and educational priorities place importance on young people of secondary school age being active, having their voices heard, and participating in their community. This paper explores an understanding of the role of agency in young people’s lives and how the concept is developing. Young people who perceive themselves as having agency may feel they have the ability to change something about themselves or their environment for a valued goal; this may increase their resilience and adaptability to life challenges.
A systematic review of agency-related literature revealed little consistency and coherence in definitions and components of agency, particularly regarding young people. Empirical research used realist grounded theory to analyse discussion of three focus groups consisting of 11 young people aged 13 to 17 involved in active school and community projects in both rural and urban areas from a large county in the UK. Findings indicate how certain psychological factors relate over time between a young person’s thoughts and feelings, their structural context and their positive interpersonal relationships to support their sense of being an agent.
This article argues that focus on young people’s agency is a key thread linking many areas of educational practice to empower young people. Implications for practice with young people, professionals and families are discussed, including use of a schema of the findings to guide assessment and intervention. 相似文献
